Hi all, Could anyone tell me if there is some package that fits any Item Response Model (further the ltm package)? Regards, Caio --------------------------------- [[alternative HTML version deleted]]
I do not believe another IRT package exists. However, I have recently used the rasch() function in ltm for a study I am doing and have found it very useful. I'm curious (as I'm sure the ltm developer is) as to what are you doing that ltm cannot handle.
